As luck would have it we met someone who lives in Hayling Island in the week leading up to our holiday so we arrived with a little local knowledge
We crossed the Langstone bridge, traversed the Island from top to bottom and arrived at "Lakeside"
We were met with an "elephant in the room"
We explored the south coastline and came across an old Ack-Ack gun placement next to a lake. The lake had an island and the island had trees and the trees had plastic bags...
which turned out to be egrets
After 3 nights we transferred (upgraded?) to Sinah Warren
...which provided opportunities for bird watching on the mudflats (heron, egret, curlew, oystercatcher, redshank, golden plover, black-headed gull, black-backed gull)
...and having been disappointed in trying to book rifle shooting and archery at Lakeside we made sure we got our names down early at Sinah Warren. Mum was able to burst balloons at archery while I was came out best at rifle shooting.
On our departure day there was a "birds of prey" demonstration. There was an awkward moment when the falconer's whole audience started looking up away from his birds when a wild buzzard arrived and started flying round over our heads. We had also seen this buzzard the day before during the archery.
